Synopsis
Hitomi decides to join the Photography & Art Club. Kohaku finally returns from England via ship and uses her magic to create an illusion of her school in London using some photos, but an oncoming train accidentally causes dust from the engine to fall all over everyone and the teacher. After school though, Kohaku informs Hitomi that the train was caused by her instead, and suspects that she has a dormant power within her. For club activities the next day, Hitomi, accompanied by Kohaku, goes to the school roof with everyone to take photos of the night skyline, wanting to create a new kind of theme for a more interesting presentation that combines both photography and art for the upcoming Cultural Festival. As first-year student Chisuga Fukasawa stays behind with Kurumi after telling her some ghost stories and scaring her, the rest proceed to the roof where in the midst of work, Yamabuki decides to distinguish between the two members of the Tsukishiro family by calling them via their first names, but Aoi decides to only call Kohaku by her first name for a distinction. After the photo shoot, Hitomi gathers up the courage to tell everyone that she is actually from the future, with Kohaku being her grandmother. The two use magic to make a train in the sky and they all return home after taking these satisfying shots.
